I started playing df with 56k. My 56k didn't bother me at all. When I got dsl it was harder, only because what Romeo Eight Jul said, you have to get used to it. And if you have been on 56k for awhile then move to cable/dsl it's hard. You won't just 'instantly improve'. Some might but for the most the only way to improve is to learn with what you got now.
I've seen so many great players on 56k, so it's not impossible. Unless you are on AOL.
This can also be reverced, people with cable/dsl can have a hard time killing 56kers, I know I do. And I die easier with dsl (Not cable cause my upload is like 56k
). But when everyone is on cable dsl your modems connect faster and you are easier to kill, if your trying to kill someone on 56k it's a pain in the ass because you have to find your lead all over again.
So when you imply 'everone that is good on 56k would own on dsl' is complete bs. And if you get cable/dsl come play with me. I'll prove it to you.
